Triggered Strobe
In Triggered Strobe mode, the unit will wait for a user generated trigger signal on the digital pins of the
multiport. This allows the user to set up a strobe train, synced with an external trigger source, to stop
motion in machine vision applications.
Note:
Strobe intensity is set by the analog dimming level set under “LED Channel Settings” section.

Below is a sample strobe train. The input is a 20 KHz, 0V Low, 3.3V High signal. The output is detected on
a reverse biased photodiode. The spread on the output pulse train is caused by the input signal falling at
different times during the 5
µ
s tick of the internal clock used to control the LED.
